LPIC-1 Exam 102 v5 (Linux Administrator) — Question 89

What is true regarding public and private SSH keys? (Choose two.)

Answer options

• A. For each user account, there is exactly one key pair that can be used to log into that account.
• B. The private key must never be revealed to anyone.
• C. Several different public keys may be generated for the same private key.
• D. To maintain the private key's confidentiality, the SSH key pair must be created by its owner.
• E. To allow remote logins, the user's private key must be copied to the remote server.

Correct answer: B, D

Explanation

Option B is correct because the private key must remain confidential to ensure security. Option D is also correct as the owner should generate the SSH key pair to protect the private key's confidentiality. Options A, C, and E are incorrect; A suggests a limitation that is not true, C falsely implies multiple public keys can correspond to one private key, and E misstates the requirement since the private key should not be copied to the server.
